#     libnvdimm, region: Use struct_size() helper in kzalloc()
#     
#     One of the more common cases of allocation size calculations is finding
#     the size of a structure that has a zero-sized array at the end, along
#     with memory for some number of elements for that array. For example:
#     
#     struct nd_region {
#             ...
#             struct nd_mapping mapping[0];
#     };
#     
#     instance = kzalloc(sizeof(struct nd_region) + sizeof(struct nd_mapping) *
#                               count, GFP_KERNEL);
#     
#     Instead of leaving these open-coded and prone to type mistakes, we can
#     now use the new struct_size() helper:
#     
#     instance = kzalloc(struct_size(instance, mapping, ndr_desc->num_mappings),
#                        GFP_KERNEL);
#     
#     This code was detected with the help of Coccinelle.
